Table 3_Association between food-related media content and the eating behaviors of Korean adults according to household type.docx

BackgroundSociocultural changes and the proliferation of digital platforms have led to the increasing popularity of food-related content in Korea, including Mukbang, Cookbang, and Sulbang. Despite concerns that such content may influence eating habits, research focusing on adults is limited. Therefore, this study examined the association between media content and eating behaviors, stratified by household type, while considering the living environment. MethodsData were derived from an online survey conducted by the National Cancer Center, comprising responses from 1,270 participants divided in a 1:1 ratio based on whether they watched food-related content. The participants reported their eating behaviors and viewing habits. Multivariable logistic regression was employed to identify relationships after adjusting for sociodemographic variables, with analyses stratified by household type. ResultsThe analysis results showed that in multi-person households, viewing all content types were significantly associated with late-night eating and delivery/take-out meal consumption, with some also related to the frequency of dining out. Conversely, in single-person households, significantly positive associations were exclusively found between Mukbang viewing and late-night eating as well as delivery/take-out meal consumption; Cookbang and Sulbang did not yield statistically significant results. In stratified analysis, more subgroups exhibited associations with eating behaviors, regardless of content type among multi-person households. ConclusionThe findings suggest that viewing food-related content is linked to dietary behaviors, with effects varying depending on household type. Furthermore, acknowledging the impact of such content on eating behaviors to explore means of utilizing it positively to foster healthy eating habits is imperative.一、研究背景 社会文化变迁与数字平台的普及推动了韩国饮食相关内容（包括吃播（Mukbang）、料理播客（Cookbang）、饮酒播客（Sulbang））的日益流行。尽管此类内容可能影响饮食习惯的担忧不绝于耳，但针对成年人的相关研究仍较为匮乏。因此，本研究结合居住环境，按家庭类型分层，探讨了媒体饮食相关内容与进食行为之间的关联。 二、研究方法 本研究数据来源于韩国国家癌症中心（National Cancer Center）开展的一项在线调查，共纳入1270名参与者，按是否观看饮食相关内容以1:1的比例进行分组。参与者需报告自身进食行为与观看习惯。本研究采用多变量逻辑回归模型，在调整社会人口学变量后分析变量间关联，并按家庭类型进行分层分析。 三、研究结果 分析结果显示，在多人家庭中，观看所有类型的饮食相关内容均与深夜进食、外卖/外带餐食消费呈显著关联，部分内容类型还与外出就餐频率相关。与之相反，在单人家庭中，仅观看吃播与深夜进食、外卖/外带餐食消费存在显著正相关；料理播客与饮酒播客未呈现统计学意义上的显著关联。分层分析结果表明，在多人家庭中，无论内容类型如何，更多亚组均与进食行为存在关联。 四、研究结论 本研究结果表明，观看饮食相关内容与膳食行为存在关联，且其影响效应因家庭类型而异。此外，明确此类内容对进食行为的影响，并探索积极利用其培育健康饮食习惯的路径，至关重要。
